This example illustrates how to model a barrel hinge connecting two solid objects in an assembly. In this model, the details of the connection are not the focus of the analysis, therefore, the hinge joint is modeled using a Joint feature in the Multibody Dynamics Module. The connected ... 詳細を見る

This tutorial model explores the behavior of a microwave plasma torch. The plasma is generated within a dielectric tube inserted in a rectangular waveguide. The simulation solves the coupled equations for plasma transport and heating, microwave electromagnetic fields, fluid flow, and ... 詳細を見る

An electrostatically actuated MEMS resonator is simulated. The device is driven by an AC + DC bias voltage applied across a parallel plate capacitor. In this example, the pull-in and pull-out voltages of the resonator are computed. This is done via a quasi-static analysis of the ... 詳細を見る

This tutorial shows how to set up a multi-element objective lens. The chosen lens is a Petzval lens with field flattener described in 'Fundamental Optical Design', by M. Kidger, 2001, pg 192. The tutorial demonstrates how to include a geometric sequence using the 'Spherical General Lens ... 詳細を見る

Compact camera modules are widely used in electronic devices such as mobile phones and tablet computers. In order to reduce both the size and number of elements required the optical design will typically incorporate several highly aspheric surfaces. This model demonstrates a five element ... 詳細を見る

This example is a benchmark problem for simulating phase change in porous media. It studies the melting process of an ice inclusion within porous media and therefore demonstrates how to couple Darcy's Law with the Heat Transfer in Porous Media interface including phase change. 詳細を見る

この非従来型の多孔質媒体流れモデルは, 多孔質媒体の隙間におけるクリープ (ストークス) 流を利用します. このモデルは, カリフォルニア大学サンタバーバラ校の Arturo Keller 氏, Maria Auset 氏, Sanya Sirivithayapakorn 氏が行った細孔スケールの流れ実験に基づいています. モデルに使用されている形状は, 走査型電子顕微鏡画像から作成されました. この例では, Keller 氏, Auset 氏, Sirivithayapakorn 氏による 2D マイクロ媒体画像の1つを使用し, ... 詳細を見る

Surface micromachined thin films are often subject to residual stress. This COMSOL Multiphysics example describes a thin film resonator with straight or folded cantilever beam springs. The resonance frequencies of the resonator are affected by thermal stress. Using folded springs ... 詳細を見る

In electromagnetic simulations, such as transformers and converter stations, one often needs to include geometrically thin conductive layers. Explicitly meshing these thin layers can be computationally expensive and numerically challenging, especially when the layer thickness is much ... 詳細を見る

This example illustrates how to perform eigenfrequency and static analyses of a ladder frame structure for a light truck. Important modeling strategies are described. For example, how to convert a solid geometry to a shell model, how to make different types of connections, and how to ... 詳細を見る
